3D Print Bed Leveling
Testing with a bigger knob on the A10
3D Touch Sensor
I had the Geeetech Sensor in operation for a while but it did not work as satisfactory as hoped. I am trying the "original" BL Touch now see http://www.BLTouch.com
Firmware 1.1.9 with BLTouch
has a link to:
that i used as a Basis. Please check the BLTOUCH_DELAY in Configuration.h which i have seen with other values in other bltouch firmwares
/** * The BLTouch probe uses a Hall effect sensor and emulates a servo. */ #define BLTOUCH #if ENABLED(BLTOUCH) #define BLTOUCH_DELAY 375 // (ms) Enable and increase if needed #endif
I compiled and uploaded things with Arduino 1.8.9 on a Mac
I ended up with a Z-Level offset of -2.28. I tried -2.4 and did a 0.15 mm DIN A4 paper test moving the Z-Axis down and still having 0.1 mm to go - the paper was a bit thight so i went for 0.02 less. With Octoprints Bed Visualizer plugin i got: which i consider decent. The print results are o.k.
I had to follow both of the following videos to get the Sensor working:
The firmware outlined in the first video is available from
Alternatives are the links below and see my own installation above.
see videos and Marlin on how to compile and flash the firmware onto the device.
